An eta/DYNAFORM session begins with one of the following scenarios:
1. The user provides CAD data (IGES, VDA, NX, CATIA or any other geometry data) that will be translated and read directly into eta/DYNAFORM database.
2. The user provides model data (e.g. NASTRAN, LS-DYNA, etc.) that will be read directly into eta/DYNAFORM.
3. CAD or model data is not provided. The user begins with a blank database and generates or digitizes the line and surface data from a drawing.
NOTE: An example of a method of supplying or generating data is outlined in Sections 2.2~2.4.
Usually, a stamping simulation includes the following steps.
